In just 24 sessions of one hour or less, Sams Teach Yourself Android Game Programming in 24 Hours will help you master mobile game development for Android 4. Using a straightforward, step-by-step approach, you’ll gain hands-on expertise with the entire process: from getting access to the hardware via the Android SDK to finishing a complete example game. You’ll learn to use the Android SDK and open source software to design and build fast, highly playable games for the newest Android smartphones and tablets. Every lesson builds on what you’ve already learned, giving you a rock-solid foundation for real-world success!
Step-by-step instructions carefully walk you through the most common Android game programming tasks.
Quizzes and exercises at the end of each chapter help you test your knowledge.
By the Way notes present interesting information related to the discussion.
Did You Know? tips offer advice or show you easier ways to perform tasks.
Watch Out! cautions alert you to possible problems and give you advice on how to avoid them.
